Description
Technical Field
The present invention relates to an apparatus and method for managing a digital video compression system, such as a Digital Video Broadcasting (DVB) system, and in particular to a method and apparatus for providing a user interface for managing such a system.
Background
a digital video compression system or broadcast television system (e.g., a digital video broadcast system) includes a plurality of interconnected devices. The interconnected devices form a network that provides a solution to meet the customer's requirements, thereby defining a system. The devices forming the network may be provided by a number of different vendors.
the purpose of any of these systems is to transform and repurpose (repurpose) signals from various sources to various destinations. In doing so, a number of transformations are applied to the signals, such as encoding, transcoding, commercial insertion, multiplexing, descrambling, scrambling, splicing or splitting of data streams, and so forth. The transformation is provided by a software application and a separate hardware resource (e.g., a different device chassis or an optional plug-in a chassis).
In older generation systems, one hardware device may typically provide a limited part of the solution and one type of transformation functionality, e.g. only encoding, but in newer systems, a hardware device may typically include multiple transformation functionality within the same hardware resources, e.g. encoding, transcoding or descrambling all within the same hardware.
The overall system (comprising a plurality of individual devices) is managed by a control system. The control system collects information from the various devices and provides a view to manage the status and configuration of the devices as a system. The user interface of such control systems is typically provided by a native user interface installed as part of the control system.
since the network of interconnected devices may be quite different, a portion of the user interface is provided by a non-native application (e.g., a device web page). Thus, the user is provided with a mix of different interface views.
the user interface needs to provide the ability to allow a user to manage the interconnections in the system, such as Internet Protocol (IP) interconnections, DVB interconnections, coding functions, multiplexing functions, and a wide variety of parameters.
In some networks, the system can be managed entirely by the control system. Although the user experience is improved in this case because the user has access to a single user interface, the way the system is configured is typically device-centric or transport stream-centric.
For device-centric configuration and monitoring in non-native systems, the user manages each device individually using its own user interface (providing such a Web interface for each device). Users typically visualize the hardware in the system and maps (maps) of its physical connections, and manage each device by using interfaces specific to each device in turn. This is a device-based paradigm.
for a transport stream centric approach, the configuration is abstracted to the input and output of the system. This is typically viewed using one or more tree-based views, since the transport stream has a logical hierarchy. This is a transport stream paradigm.
This hardware view can also be used for monitoring purposes, in case the control system provides a graphical 'map' of the devices in the system, showing each device and its connection to the subsequent device or devices.
User interaction (user experience) is disjointed as a result of the different user interfaces provided by the system. That is, the user must view a number of different user interfaces, configure the devices in turn or configure the system using portions of the native control user interface provided by the control system.
In the case where the control system provides a device-centric approach, the user experience remains disjointed. Data may need to be entered into different device user interfaces, thus having the disadvantage of requiring repeated data entry, and each device type has partially different ways or abstractions to manage its overall system configuration.
In the case where the approach is transport stream centric, configuration and monitoring still does not provide a way to manage (configure or monitor) the system across all the transformation functions in a single view-multiple views may need to be initiated to accomplish the task. In addition, users are often forced to search through various property pages and tabs in order to locate properties to accomplish a particular task.
Fig. 1 is an example of a device-centric approach, whereby a list of network devices (e.g., input nodes 101, switches/routers 103, encoders/transcoders 105, multiplexers 107, output nodes 109) and their physical connections are shown. These views are provided on the user interface in the form of a map of the hardware in the system, as shown in fig. 1, but this has the disadvantage of being limited to the physical devices and their interconnections.
disclosure of Invention
it is an object of the present invention to provide methods and apparatus which obviate or mitigate at least one or more of the above disadvantages.
according to a first aspect of the present invention there is provided a method of providing a user interface for managing a digital video compression system. The method comprises the following steps: receiving system configuration information associated with a digital video compression system being managed; and dividing the system into a plurality of transform stages, each transform stage representing a transform that can be performed on the signal stream as it flows through the system. The method further comprises the steps of: the signal stream is represented using one or more signal blocks, wherein the signal blocks contain information related to the signal stream within the transform stage. A view of the system is generated, where the view of the system is represented as one or more signal streams through the system and one or more signal blocks along each of the signal streams. The method also includes the step of modifying the view of the system in response to a user command.
The advantage of this approach is that it presents a conceptual model of how signals are passed through the transmission stages and signal blocks of the system, i.e., based on the purpose of the system, rather than showing only the hardware interconnect.

The processing unit is configured to divide the system into a plurality of transform stages, each transform stage representing a transform that can be performed on the signal stream as it flows through the system.

The processing unit is further adapted to modify the view of the system in response to a user command.

Detailed Description
Fig. 1 illustrates a method for providing a user interface for managing a digital video compression system according to an embodiment of the present invention. The method includes the step of receiving system configuration information associated with a digital video compression system being managed (step 201). At step 203, the system is divided into a plurality of transform stages, each transform stage representing a transform that can be performed on the signal stream as it flows through the system. In step 205, the signal stream is represented using one or more signal blocks, wherein the signal blocks contain information related to the signal stream within the transform stage. A view of the system is generated (step 207), wherein the view of the system is represented as one or more signal streams through the system, and one or more signal blocks along each of the signal streams. The view of the system is modified in response to receiving a user command (step 209).
This approach simplifies the complexity of many signals being managed through the system and provides a view of the system that relates signal management to the intended purpose of the system rather than the interconnection of hardware.
this has the advantage of providing a conceptual model of how signals are passed through the transmission stages of the system, i.e. based on the purpose of the system and not just the hardware interconnect.
fig. 3 shows an apparatus 30 for providing a user interface for managing a digital video compression system according to an embodiment of the invention. The apparatus comprises a receiving unit 31 adapted to receive system configuration information related to the digital video compression system being managed. The apparatus 30 further comprises a processing unit 32 configured to divide the system into a plurality of transform stages, each transform stage representing a transform that can be performed on the signal stream as it flows through the system. The processing unit is further configured to represent the signal stream using one or more signal blocks, wherein the signal blocks contain information related to the signal stream within the transform stage. Further, the processing unit 32 is configured to generate a view of the system (where the view of the system is represented as one or more signal streams through the system, and one or more signal blocks along each of the signal streams), and to modify the view of the system in response to user commands.
a more detailed explanation of the method and apparatus of the present invention will now be provided with reference to fig. 4 to 29, and in particular how the system view is generated after the system is partitioned and represented as described above, and how the system view can then be modified in response to user commands. These figures visualize the interactions and concepts for configuring and/or monitoring the user interface of a digital video compression system, in accordance with embodiments of the present invention.
referring to fig. 4, in accordance with an embodiment of the present invention, the step of generating a view of the system may include the steps of arranging the transform stages 51 into a series of horizontal stages (51 1 through 51 3 in the example of fig. 4) and arranging the signal blocks 53 into vertical columns of signal blocks within the transform stages of the example of fig. 4 include a "describe" transform stage 51 1, an "encode" transform stage 51 2 and a "multiplex" (mux) transform stage 51 3 it is noted that any number of transform stages may be provided and relate to any mix or combination of transform functions in the example of fig. 4, only one row of signal blocks 53 1 is shown in the column corresponding to transform stage 51 1, while multiple rows of signal blocks 53 11 through 53 41 are shown in the example of fig. 5 for the column corresponding to transform stage 51 1, and the same for the other transform stages.
Embodiments of the present invention provide a map view approach in which physical and logical signals are passed through transform stages in the system, and each signal stream is represented by one or more signal blocks along each signal stream. This arrangement enables a user to pan (pan) and/or zoom in order to enable a small screen to view the system and facilitate spatial perception of the user.
in such a method or apparatus, the view of the system is modified by translating along the path of the signal stream in response to receiving a translation command from the user.
As the user pans and zooms through the flow of graphical signals in the system, detail is added or removed depending on the zoom level (or hierarchical level). In addition, the content of the view is changed via the user selecting a different information layer in the system, as will be explained below.
the view of the system shown in fig. 4 includes a single signal stream 50 1, such as the video stream "ABC 1" conveyed through the transform stages 51 1 through 51 3 (signal stream 50 1 is identified as 50 11 through 50 13 in the respective transform stages 51 1 through 51 3), signal blocks 53 1 through 53 3 visualize the processing performed on signal stream 50 1 in each pair of transform stages 51 1 through 51 3, in an example, each signal block is shown displaying a service identifier (e.g., ABC1, ABC2, SPORT 1, MOVIES 1, etc.) identifying the service provided by the signal stream, device equipment information (e.g., encoder, mux, splitter, etc.) identifying the transform operation performed on the signal stream by one or more device equipment, and internet protocol multicast information (e.g., IP multicast address information).
For example, signal block 53 1 is shown to display a service identifier "ABC 1", device information corresponding to "1080/MP 2/8 Mbps" (i.e., identifying the video signal stream as a 1080 high definition signal stream in MP2 format and having a data rate of 8 Mbps), and internet protocol multicast information "239.0.0.1" (which includes an IP multicast address corresponding to this signal block 53 1). signal block 53 2 shows that, in the transformation stage 51 2, in the case of performing an encoding function, signal stream 50 11 undergoes an encoding function from MP2 to MP4 format, wherein the data rate is converted from 8 Mbps to 6 Mbps. thus, signal block 53 2 shows the service identifier "ABC 1" for identifying the signal stream, device information corresponding to "1080/MP 4/6 Mbps" (i.e., identifying the video signal stream as a 1080 high definition signal stream in MP4 format and having a data rate of 6 Mbps) and protocol information corresponding to "MP 5" (which includes a 1080 high definition signal stream corresponding to this signal stream, and which is a signal stream of which is a multiple signal stream of multiple signal blocks of multiple signal streams — this signal blocks of multiple signal blocks of a signal blocks representing multiple streams of multiple IP signals, which are multiplexed signals, thus, the case, the multiple signal blocks of multiple signal blocks representing multiple signal blocks of multiple signal.
As can be seen from the above, embodiments of the present invention are configured such that the signal block comprises information, including any one or more of the following: a service identifier (e.g., ABS, Sport 1, Movies 1) for identifying a service provided by the signal stream; device information (e.g., encoder, mux, splitter, etc.) identifying a transform operation performed on the signal stream by one or more device; and internet protocol multicast information (e.g., IP multicast address information) for the signal stream.
Fig. 5 shows a view including a plurality of signal streams (e.g., a first signal stream 50 1 corresponding to a television video signal ABC1, a second signal stream 50 2 corresponding to a television video signal ABC2, a third signal stream 50 3 corresponding to a television video signal SPORTS 1, and a fourth signal stream 50 4 corresponding to a video signal movie 1).
The system is divided into a plurality of transform stages 51 1 to 51 3, each representing a transform that can be performed on the signal stream 50 as it flows through the system, each signal stream 50 is represented using one or more signal blocks 53, where the signal blocks contain information relating to the signal streams within the transform stages, thus, the view of the system in FIG. 5 is shown as one or more signal streams 50 1 to 50 4 through the system, and one or more signal blocks 53 along each of said signal streams 50 1 to 50 4.
FIG. 5 shows how a system view can be modified in response to user commands 70 1. user commands allow a user to translate through the system view in any direction, for example to see which functions have been performed on each signal stream upstream or downstream of a particular view, or to determine which other signal streams may exist above or below the current view of the signal stream.
FIG. 6 shows an example of a system view whereby a user command 70 2 is received to display a visualization of what is happening to the signal flow downstream of the system view shown in FIG. 5. accordingly, signal blocks 53 14 through 53 44 are represented in the system view further translation in the downstream direction will identify further information about signal blocks 53 14 through 53 44, as will be seen from the following figures (e.g., FIG. 8).
Fig. 7 shows an example of a system view whereby a user command 70 3 is received to display a visualization of what is happening to the signal flow below the system view shown in fig. 5, thus, the signal flow 50 5 corresponding to the signal flow move 2 is displayed.
FIG. 8 illustrates an example of a system view whereby a user command 70 4 corresponding to a zoom-out command is received to display more signal streams in a given system view than in the example of FIG. 5.
FIG. 9 shows an example of a system view whereby a user command 70 5 corresponding to an additional zoom-out command is received to display even more signal streams in a given system view than the example in FIG. 5.
as can be seen from the above, the apparatus and method of the present invention can provide a plurality of hierarchical layers, in which a first level of information is displayed in a signal block of a first hierarchical layer and a second level of information is displayed in a signal block of a second hierarchical layer.
This has the advantage of enabling the hierarchical layers to provide different levels of detail for the various transform levels (i.e. when the user zooms in and out on the system view).
the system view in such embodiments is modified by switching between hierarchical layers in response to receiving a user command (i.e., in response to receiving a zoom-in or zoom-out user command from a user).
as an additional or alternative feature of fig. 8 and 9, it is noted that the user may also configure the system to have different font sizes when zooming in/out. For example, when receiving a zoom-in command from a user, the system may be configured to initially display the same level of detail as the previous zoom layer in each signal block, but with information initially displayed in a different font size (i.e., a smaller font size) before beginning to omit information upon further zoom-in.
For example, in FIG. 10, signal block 53 11 only displays the multicast IP address, rather than only the service identifier ABC1 as shown in FIG. 9.
as can be seen from the above, the apparatus and method according to embodiments of the present invention may further include providing a plurality of information layers, wherein a first type of information is displayed in the signal block at a first information level and a second type of information is displayed in the signal block at a second information level.
the view of the system can be modified by switching between information layers in response to receiving a user command.
This has the advantage of enabling the information layers to provide different types of information (e.g. DVB services, IP, stat mux, etc.) for the various signal blocks, which can be switched in response to receiving a user command.
Fig. 11 shows how the redundant grouping can be displayed either by layer selection or by further reduction. Fig. 11 shows a first redundant grouping 132 and a second redundant grouping 133.
thus, in such embodiments, the step of modifying the view of the system includes switching to displaying the redundancy grouping by either selecting an information layer (i.e., selecting a layer) or selecting a hierarchical layer (i.e., further zoom-out command) in response to a user command.
In fig. 12, the system can be configured to display redundancy protection in view (without or with a backup as shown in this example), for example by adding a border color or other visual effect to the redundant grouping (e.g., solid lines for the redundant grouping 132 and dashed lines for the redundant grouping 133 as shown in fig. 12). Any form of visual effect may be used, including different colors as described above.
thus, in such embodiments, the step of modifying the view of the system comprises switching to displaying redundant protection in the event that no backup device is available and thus no protection is currently available.
with this redundant grouping arrangement, the boundary encompasses a group of cells (cells) or signal blocks that share the same redundant grouping. A redundancy grouping defines a set of devices that can be used for a particular set of transform functions.
For example, if signal block 53 32 of FIG. 13 has a worst health status, signal block 53 32 can be displayed using a different visual effect (e.g., a different color or flashing effect), and the corresponding title of transformation stage 51 2 is also displayed using a visual effect (e.g., a different color or flashing effect).
In such embodiments, the step of modifying the view of the system includes using different information layers to represent different levels of operational efficiency (i.e., health) of the signal blocks, and highlighting signal blocks having operational efficiency (e.g., at risk) below a threshold.
thus, referring to FIG. 14, when the user's attention is thus brought to the signal block 53 32, upon receiving the user command 70 9 to zoom in to this signal block 53 32, additional details of the signal block 53 32 having an unhealthy state can be displayed, thus enabling the user to perform any diagnostics and more detailed analysis that may be required.
Fig. 15 shows still further details of how a signal block 53 32 having a poor health status can be displayed upon receipt of a user command 70 10 to further zoom into the signal block 53 32, and the sub-signal blocks 53 32A and 53 32B associated with the signal block 53 32 will be displayed, thus enabling the user to perform any diagnostics and even more detailed analysis that may be required.
As can be seen from fig. 13, 14 and 15 above, the user can initially zoom out and then pan the system view in order to locate the transform stage and corresponding signal block that needs attention, and then zoom in to the signal block in question once identified in order to perform the desired diagnosis.
Thus, the embodiments of fig. 13-15 provide status information that is displayed on each signal block if the signal is corrupted or is below a certain operating efficiency within the transform stage. This can be displayed via a visual effect (e.g., colorization of the signal block as described above). The state information may also be propagated to the header blocks of the transform stage to further enhance the visual alert to the user. The system can be configured such that the highest severity alert color is prioritized over the transform title block.
FIG. 16 shows how the system can be configured to switch layers in response to receiving a user command 70 11 in order to display video thumbnails 56 of one or more signal streams.
fig. 17 illustrates how the system can be configured to perform editing functions online (inline) within a system view in response to receiving a user command 70 12.
For example, as shown in FIG. 18, in response to receiving a user command 70 12 to perform an editing function online within the system view, such as by clicking, double-clicking or touching the display (or any other way of selecting the signal block in question), a property panel 181 of the extension setting to be edited by the user is presented.
Fig. 19 illustrates how the system can be configured to perform multiple selections in response to receiving user command 70 13, so that changes can be made to any two or more signal blocks at a time simultaneously.
in accordance with another aspect of the invention, FIG. 20 shows how a system view is searched in response to a user command 70 14 the present example shows how a user can search for a particular item in the system view, such as "MOVIES 2" in the present example, where the system is configured to then pan to that item, such as signal block 53 52 (if found).
With this arrangement, the user can find items in the view by using the find edit box, button. Matches with the search text are shown in the view by visual effects such as colorization and border highlighting of the matched cells. The user can enumerate (enumerate) additional matches via the next or back button. In the event that an item is out of view, the system is configured to pan and/or zoom to present the item (if found).
According to another aspect of the invention, FIG. 21 shows how a system can be configured to classify features shown in a system view in response to receiving a sort command 70 15 from a user.
in accordance with another aspect of the present invention, FIG. 22 illustrates how the system can be configured to filter displayed information in response to receiving a filter command 70 16 from a user.
Thus, the step of modifying the system includes the step of filtering information displayed in a particular view in response to receiving a filter command from a user. With this arrangement, the view can be filtered to show signal flow that matches only signal blocks or cells that include filtered text. The filter text is entered in the filter edit box. The unmatched signal flows are removed from view or obscured (which may be provided to the user as an optional option).
In accordance with another aspect of the present invention, FIG. 23 illustrates how the system can be configured to use a wizard assist function 2301 during the setup process in response to receiving wizard assist commands 70 17 from the user.
In accordance with another aspect of the invention, FIG. 24 shows how the system can be configured to alter the representation of the signal stream in response to receiving a drag-and-drop command 70 18 from a user.
Thus, fig. 23 and 24 describe an embodiment that further comprises the steps of: receiving a user command to edit a system setting; modifying the system settings accordingly; and updating the view of the system based on the modified settings. The system settings may be modified in response to a user selecting a corresponding signal block and editing system parameters for that signal block, or a user selecting multiple signal blocks and editing system parameters for multiple signal blocks in parallel.
FIG. 25 shows how additional layers allow rearrangement (or transition) of system views under hardware-centric grouping, e.g., the parent of signal block 2501 is shown as a device, with the services carried by the device shown as subsystem blocks 53 32X and 53 32Y.
Fig. 26 shows how the system view may be rearranged into a statistical multiplexer group (referred to herein as a "Stat Mux" group), such that the Stat Mux group is the primary group, and such that the contribution (distributing) signals entering the group are then arranged in the Stat Mux group. According to statistical multiplexing, services have their video adjusted to a variable bit rate based on the quality of the coded pictures. stat mux marshalling controls the total bandwidth that the marshalling will limit according to the bit rate. A Stat Mux activity bar can also be displayed to show the activity of the multiplexers. With this arrangement, the signal blocks in the view are rearranged (via transition animation) under the parent cell (which represents the stat mux grouping that the signal flow is contributing to). In other words, the signal blocks are organized according to how their relationships of the services shown by the signal blocks are carried in the multiplexer. The multiplexer organizes a set of services into a set called Transport, so the view allows signal blocks to be so ordered in the context of a Transport group of multiplexers or their child 'Stat' multiplexer group within a Transport.
fig. 27 shows how the system view can be configured to show, for example, an additional path 2700 where the signal 50 32 splits (e.g., due to a duplicate path.) thus, in the event of a signal stream or signal path split, the system view is configured to render this behavior.
FIG. 28 illustrates how duplicate paths may be presented with duplication of transform stages, thus allowing the system view to preserve grouping within transform stages (transmission of grouping in the example of FIG. 28.) for example, in FIG. 28, a signal stream with signal blocks 53 21 and 53 22 is shown with duplicate paths with signal blocks 53 21' and 53 22'. thus, service ABC2 is replicated with two transmission duplicate signal blocks, each marked with a visual indicator (e.g., "split icon"), and/or colored differently, for example, to indicate that there is only one actual resource for these duplicate paths.
Additional details will now be provided regarding how the system may be configured.
fig. 29 illustrates a digital video compression system 3100 (e.g., a broadcast system) that includes a broadcast device (e.g., a DVB device). Fig. 29 also shows a digital video compression control system 3102, such as a broadcast control system, and a user 3101, according to an embodiment of the invention.
the digital video compression control system 3102 is configured to build the definition of the system at step 3105. This may involve importing information 3103 to help define the system. The imported information can include information related to the resources of the system, the transformation capabilities of those resources, the attributes of the system, and the state of the resources within the system. The information may be imported (i.e., programmatically discovered) by querying the broadcaster. The interrogation of the system may involve logging into the command and control interfaces of the various appliance devices in the digital video compression system and retrieving some or all of the information available from the interfaces. If information relating to the overall system is not available in this manner, information 3104 from user 3101 may also be received to help configure the system.
At step 3106, the digital video compression control system is configured to build a system model, for example, by dividing the system into multiple transform stages and signal blocks as described above. At step 3107, the system is configured to render a view of the system model, and to present or display the view to the user at step 3108.
FIG. 30 illustrates updating a data model and view of a system when a user makes a change to the system or the system itself responds to a change (e.g., a status event). At step 3205, the digital video compression control system is configured to receive information related to system changes, or in the form of status or dynamic system change information 3101 from the digital video compression device 3100 and/or system configuration information (changes) from the user 3101. In response to changing the system at step 3205, the system model is then updated at step 3206, for example by dividing the system into transform stages and signal blocks as described above. At step 3207, the system is configured to render a view of the updated system model, and to present or display the updated view to the user at step 3208.
FIG. 31 shows how the actual view is the entry into the data model of the rendering system. The actual view renders whichever of the results of the "view model". When a partial view of the system is to be viewed, a cropped area of the system is defined and the "view model" is updated. This process is illustrated in fig. 31, which shows functional units 3302 used to construct a particular view. The functional units interface with the digital video compression or broadcast device 3300 to receive dynamic changes or states of the system and have user interactions 3304 with the user 3301. At step 3305, a crop area is determined based on the crop area selected by the user. At step 3306, a system model is generated, and at step 3307, a view model is generated for the selected clipping region. At step 3308, the view objects from the system model are reused with the view model associated with the cropped area so that at step 3309, an updated view associated with the cropped area can be rendered.
In accordance with the embodiment of FIG. 32, the digital video compression control system includes a software driver 3406 configured to discover and configure devices within the system for each device type, hi this example, this involves communicating with a first device apparatus 3400 1 over a communication link 3405 (e.g., XML over HTTP), communicating with a second device apparatus 3400 2 over a communication link 3404 (e.g., HTML over HTTP), and communicating with a third device apparatus 3400 3 over a communication link 3403 (e.g., binary over TCP).
note that smaller views have fewer drivers, which in turn may result in fewer transform stages in the system. Likewise, a larger view may have more drivers, which in turn may result in a larger number of transform stages in the system.
the driver is configured to communicate with the appliance device via the device's command and control interface. This enables the properties and configuration of the device to be read and written, and also enables the health status of the device to be determined.
each driver may understand different types of protocols, e.g. SNMP, XML, TCP, HTTP. Each driver may also have knowledge of the device content within the protocol and any structure of data exchange over the protocol.
Thus, as can be seen from the above fig. 29 to 32, according to an embodiment of the present invention, the step of receiving system configuration information includes the step of receiving configuration information related to the equipment devices forming the system. The configuration information may include, for example, information related to the interconnection of the device apparatuses, the processing capabilities of the device apparatuses, and status information related to the device apparatuses.
The configuration information can be received in response to querying the system to automatically determine at least a portion of the configuration information, and/or to receive at least a portion of the configuration information from a user. The interrogation of the system may involve logging into the command and control interfaces of the various appliance devices in the digital video compression system and retrieving some or all of the information available from the interfaces. The information manually entered by the user may include, for example, information relating to the interconnection of the equipment device if this cannot be determined automatically or other information relating to the equipment device.
According to embodiments of the present invention, there will typically be a limited number of types of users who view the system view. Each type of user will have a different use case to address. For example, an "operating user" is a user who assumes the management system to ensure that it functions properly. A useful use case for this view is to add or change the number of services in the system. For example, an operating user may be requested to add several services during a 'service window' (e.g., an earlier time in the morning when the risk of high-value content is limited). Embodiments of the present invention allow an operating user to make such changes using an improved user interface.
Other types of users are network and operating users. In some tv service provider organizations, there are different departments of networking and operation. The networking will be responsible for the infrastructure IP architecture as a whole and the operation responsible for the broadcast/digital television equipment. This view may be used by a user during troubleshooting or diagnostic events. There are two of a number of use cases where the new view is useful. The adjusted and layered single service-centric view facilitates both use cases by displaying the correct level of information that the user wishes to see.
Within the transform stage of the above embodiments, the transform stage may be configured to any one or more of the following operations: encoding operation; a decoding operation; carrying out transcoding operation; a multiplexing operation or a splicing operation; demultiplexing or separating operations; a scrambling or descrambling operation; and an ad insertion operation. It is noted that other transformation operations may be performed without departing from the scope of the invention as defined by the appended claims.
furthermore, it can be seen that embodiments of the present invention enable any one or more of the following features to be performed: searching and highlighting elements of the system in response to a search command received from a user; classifying signal blocks within the transform stage in response to a classification command received from a user; setting a new signal path in response to one or more commands received from a user; copying system parameters from one signal block to another signal block in response to a drag-and-drop command received from a user; providing an information layer having a parent signal block corresponding to a hardware-centric view of a device apparatus, wherein one or more child signal blocks correspond to a service carried by the device apparatus; rearranging the signal blocks into a statistical multiplexer grouping view; highlighting the repeated signal path.
Embodiments of the present invention enable the layers of a system view to be switchable to relay (relay) different information to a user. For example, switching between DVB-based views and IP-based views or switching between hardware arrangements.
Embodiments of the present invention provide a system view that is based on the purpose of the managed system, that is, the user interface presents the user with a conceptual model of how signals are passed through the transform stages or blocks in the system. Those transform stages are not limited to some physical hardware but may also include software functions or a combination of both.
the customized view provided by embodiments of the present invention separates the transformation level of the system into a horizontal arrangement. Each transform stage is capable of being skewed and represents a column of a signal passing through the transform stage. A signal is represented by a series of elements or signal blocks connected to each other. Each signal block or unit contains some data that is coherent with the signal within the transform stage. The end-to-end signal passing through the system is represented by connected signal blocks (forming a signal flow) across the transform stages. Each signal flow can be shown on its own row.
Signal blocks or cells can be arranged in parent/child signal blocks to represent logical relationships of data. The signal block can display an image to represent the type of information, such as a video icon, an audio icon, a CA vendor trademark, etc. The system view can be translated horizontally and vertically to show more signal blocks, signal flows, or transform stages. This presents the user with the illusion of an entry into the system's much larger signal map.
The customized view can zoom in or out. When the view is reduced, the data inside the signal block size is reduced and the signal block size is reduced. More signal blocks and signal flow can then be seen. As the view zooms in, more data is added to the signal block and the signal block size increases. Fewer signal blocks and signal flows are shown.
the translation can be accomplished using a mouse pointer, whereby the user mouse left clicks on the view, holds, and moves. The view moves at the same speed as the interaction performed by the user. Translation is also accomplished using the same operations as a touch interface and a single touch slide gesture, and mouse interaction, occurs.
zooming can be accomplished using a mouse pointer, whereby the user uses a mouse wheel to increase or decrease zooming (wheel increasing up, wheel decreasing down). If no mouse wheel is present, holding the left CTRL key followed by the mouse up/mouse down will achieve the same effect with the left mouse button held. The view zooms at the same speed as the interaction performed by the user. For touch interfaces, a pinch gesture is used.
the pan and zoom interaction can be configured to continue after the user interaction has stopped but the effect of the interaction rapidly decreases over time (inertia of a few seconds). This allows for fast movement around the view.
The data and information contained in the signal block can be switched to alternative data information by the user clicking on the layer button. Hierarchical buttons can be provided to allow data to be viewed in different formats, including some or all of the following information.
The service information can include one or more of the following: a service name; a service identifier; bit rate of its DVB components; and the codec used. Some internet protocol information (e.g., multicast addresses and ports) can be made viewable to the user, where appropriate.
Other internet protocol information that is made viewable can include one or more of the following: IP multicast source, destination, UDP/RTP port. It is also possible for the apparatus and method according to embodiments of the invention to control the IP address where appropriate.
Embodiments of the present invention have the advantage of making it easier to navigate large data sets, as the user is able to pan/zoom to locate the data to be viewed/altered. This is aided by the manner in which the system view relates to the system's purpose (as opposed to a hardware-centric view). The user can change the purpose of the system and the signal flow is matched to this. Status and configuration information can also be provided in a single view.
Embodiments of the present invention also enable the layering and filtering of data within a single view in a manner consistent with desktop (e.g., mouse) and mobile (e.g., touch) interfaces. When the signal flow is rearranged, switching between the layers causes a transitional effect. This all helps the user to perceive what the system is trying to achieve and is thus easy to manage.
Embodiments of the present invention can be used in a maintenance function whereby a user can add services or make changes to content in a single view by changing hierarchical information and making changes to the system configuration.
Embodiments of the present invention can be used in a diagnostic function whereby a user can see status information within a view and it is a more efficient method to perform corrective actions, for example by: redundant switching, changing configurations, adding replacement services, etc. The user can also see a more direct relationship to the impact of status (health) issues, as this involves services and signals (as opposed to hardware)
). However, views allow those views to be switched within the view to preserve the context in which the user is located.
Embodiments of the present invention have the advantage of providing a solution whereby signals are managed across systems in a federated manner and a single view of the transformation functionality across systems is provided. Embodiments of the present invention provide an intuitive solution and thus simplify the use of the system.
it should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. The word "comprising" does not exclude the presence of elements or steps other than those listed in a claim, "a" or "an" does not exclude a plurality, and a single processor or other unit may fulfil the functions of several units recited in the claims. Any reference signs in the claims shall not be construed as limiting the scope.
